Correct Answer:
B. 1919
The Treaty of Versailles was signed on June 28, 1919, officially bringing an end to World War I between the Allied powers and Germany. This foundational document established the terms of peace and laid out significant reparations and territorial adjustments.
- 1918 was the year the armistice was signed on November 11, ending the fighting, but the formal peace treaty was concluded the following year.
- 1920 and 1921 are incorrect as the treaty was already in effect and being implemented by these years.
